Question 29 Exponents and Powers - Exercise

(6/13)10 ÷ [(6/13)5 ] 2 = (6/13) ________.

Answer:

(6/13)10 ÷ [(6/13)5 ] 2 = (6/13)0

In the given question first consider [(6/13)5 ] 2

For any non-zero integers ‘a’ and ‘b’ and whole numbers m and n,

(am) n = amn

[(6/13) 5 ] 2 = (6/13)(5 × 2) = (6/13)10

Then, (6/13)10 ÷ (6/13)10

For any non-zero integers ‘a’ and ‘b’ and whole numbers m and n,

a m ÷ an = am–n , m>n

(6/13) 10 ÷ (6/13) 10 = (6/13) 10 - 10
